Friday Stats: Custom tools to analyze OpenJDK

Friday Stats is a collection of custom small utilities
for analyzing the OpenJDK code base. The name is a reference to a
tradition of writing such utilities on a Friday and publishing the
results in emails entitled Friday Stats: ...

Remove the expected set of "informational" messages from a build
log, leaving the set of messages that deserve attention. The number
of such lines is also generated, to facilitate generating a trend
graph to monitor progress over time.

Report on the number of lint and doclint messages found in a
given set of packages in a project. The program uses javac to
analyze the source code for the packages, and then creates a
summary table identifying the number of each different type of
message for each package that was analyzed.

In general, these utilities are intended to be suitable for use
both by developers, as part of their everyday work environment, and
in continuous integration environments, such as Hudson or Jenkins.
